Synopsis
Dry weather under high pressure will continue until rain
chances return with weekend low pressure. Strong winds are also
expected on Sunday.

Near term until 6 pm this evening
Expecting some decrease in the mid high level clouds over the
region this afternoon as moisture with an advancing shortwave
across the tn valley to the mid atlantic region sinks s. Dry
weather is expected today under building sfc high pressure, as
high temperatures climb to near seasonal levels.

Short term 6 pm this evening through Sunday night
A trough is progged to advance from the wrn CONUS to the plains
region Saturday. Increasing moisture and shortwave support in sw
flow aloft ahead of the trough should result in rain chances
returning late tonight, and increasing on Saturday. There could
be a brief period of freezing rain in cooling upslope SE flow
Saturday, though confidence in this occurance is low as models
continue a trend of slowing the arrival of the precip.

The trough is expected to track from the plains to the upper
great lakes by Sunday, as a developing sfc low takes a similar
path. Rain should become widespread Saturday night as the sfc
low pulls a warm front N across the region. The low's associated
cold front is expected to cross the region Sunday morning.

Widspread rain should end by Sunday morning, though a few
showers remain possible as a shortwave embedded in the main
trough approaches the upper oh valley region. A few snow showers
are possible Sunday night N pit until the passage of the wave.

Total rainfall is expected to range from 1 2 to 1 inch, with the
highest amounts S of I 70. Localized flooding is possible in
this area as creeks and strems are already elevated.

The biggest impact of the weekend is expected to be strong wind
gusts on Sunday and Sunday night with a tight pressure gradient
on the WRN side of the departing sfc low, strong pressure rises
occur, and mixing begins. Issued a high wind watch for the area
for this period. Bufkit model profiles and old rules of thumb
indicate the potential for 50-60 mph gusts across the forecast
area. Issued a high wind watch for this potential.

Long term Monday through Thursday
Dry weather should return Monday under weak ridging. Precip
chances return Tuesday night Wednesday as a trough tracks se
across the area. Weak ridging returns dry weather for Thursday.

Model ensembles and wpc progs were used for the long term
period, to smooth out the sometimes significant operational
model run differences.

Aviation 08z Friday through Tuesday
Vfr conditions are expected under high pressure through the taf
period. Only mid and upper level clouds are expected as a mid-
level wave passes to our south. Wind will remain light, drifting
to a more north northeasterly direction with time.

Outlook
Restrictions are likely in rain late Saturday as low digs
toward the great lakes and invokes strong southerly flow across
the upper oh region. Dangerously windy conditions are expected
for Sunday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
